Hi cotmyeye,
I believe it should. If there are images stored within your account that are being used in active "GTC" store listings that also reflect "0" in the "Listings" column on your "Manage Images" page, can you please let me know the URL of the image and the item number in which it is currently being used.
If you would prefer not to share this example on this public forum, please let us know by contacting our customer support department using the appropriate link on our help page: http://www.auctiva.com/free-auction-software-help/help.aspx
